SMPROVEMENT IN HAT-POUNCING MACHINES.

Specification forming part of Letters Patent No. 111 5,680, dated March17, 1874; application filed April 4, 1873.

To all whom it may concern:

Be it known that I, RUDOLF EICKEMEYER, of Yonkers, in ythe county ofVestchester and State of New York, have made an invention of certain newand useful Improvements in Machines for Pouncing Hats; and that thefollowing is a full, clear, and exact description and specification of'the same.

The object of the invention is to render pouncing-machines more compact,and to enable their members to be adjusted to the various circumstanceswhich arise in their practical operation; and the invention consists ofcertain combinations and arrangements which are specified in detail atthe close of this schedule, and some of which may be used separatelyfrom the others, if found expedient. The said combinations may begreatly varied in appearance without changing them substantially byvarying the con struction of the mechanism by which the members of thecombinations are combined, and by the use of equivalents; but, in orderthat the invention may be fully understood, I have represented in theaccompanying drawings and will proceed to describe a pouncing-machineembodying the various combinations and arrangements in the best formknown to me at present.

Figure l represents a plan of the said machine with the suction-piperemoved. Fig. 2 represents a side view of the pouncing-roller and bedand their appurtenances with certain parts of the machine removed toexhibit its internal construction. Fig. 3 represents a side view of thefeed-rollers and their appurtenances with certain portions of themachine removed. Fig. 4 represents an end view of the fan-case with theend plate removed.

The members of the machine which operate directly on the hat are the bedA, which supports it, the pouncing-roller B, which carries thesand-paper or other pouncing material and applies it to the hat; and theconical feedrollers C C', which canse the hat-body to revolve upon thebed A and draw it through between the bed A and the pouneing-roller B.All of these members are connected with the main frame D of the machine,or that frame which sustains the shaft of the pouncinglroller. Thepouncing-roller B is secured to a shaft, E, which is constructed.A torevolve in suitable bearings, a c', secured to the main frame, and isfitted with a belt-pulley, F, to which the driving-belt is applied. Thisshaft is extended beyond the rear bearing a and the fan-wings G, forcarrying off the dust from the hat, are arranged upon it, so that thesame shaft performs the two offices of pouncing-roller shaft andfan-shaft, and that the pouncing-roller and fan can be operated by thesame belt-pulley and driving belt. The fan wings are surrounded by afan-case, G', which may be of the ordinary volute form; and the eye ofthis case communicates with a suction pipe, H, which is extended to thepouncing roller B, and terminates there in a mouth, d, that extendsabove the said roller. This suction-pipe is jointed at b, so that itsmouth may be raised from the pouncing-roller sufficiently to be out ofthe way when required 5 and the mouth is readily raised or lowered andsupported in either position by means of an oscillating elbow-rest,f.

The pouncing-roller is of the usual conical form, and its barrel iscovered, by preference, with india-rubber, so as to hold the sand-paper.

Below the pouncing-roller B is the bed A, which supports the hat duringpouncing. This bed is combined with the pouncing-roller by beingconnected with the main frame D through the intervention of a movablesupport, which, in the present machine, has the form of an arm, M, whichis pivoted at its inner end of the main frame, so that its outer end andthe bed secured thereto can be lowered to permit 0f the application ofthe hats to the bed, and can be raised to press the hats against thepouncing-roller above. The arm Mis guided in its movement by beingconfined in a slot in the front end of the main frame. The bed is raisedand lowered by mea-ns of a treadle, J, to which the foot of the operatorcan be applied, and the distance to which it can be raised is limited bya regulating-screw, g, so that the pressure of the hat against thepouncing-roller cannot be made excessive, as the Contact of the point ofthe regulatingscrew with a projection of the frame above limits thedistance to which the bed can be raised. The combination ofthe bed withthe pouncingroller by means of the movable arm and the regulating-screw,or some equivalents therefor, enables the distance of the bed from thepouneing-roller to be adjusted to suit hats of different thicknesses.Hats vary in thickness from the brim to the tip, and the variation indifferent lots of hats differs. :In order to adapt the machine to suchdifferences, the bed A is connected with its support or arm M by meansof a pivot, c, so that the bed can be so tipped upon the support M thatthe surface of the former can be more or less inclined to the surface ofthe pouncing-roller, to suit the differences in thickness of the hats.rIhe tipping is adjusted by turning the nut h of the tippingscrew h1,and the surface of the said nut is held in contact with the under sideof the support or arm M by means of a sprin g,` 71.2, which in thisinstance is made of india-rubber. The feed-rollers G C are arranged atone side of the pouncing-roller and bed, and they are fitted to spindlesI I', which are inclined to each other, and are supported in thebearings of a supplementary or feed-roller frame, K, so that theadjacent conical surfaces of the feed-rollers may press simultaneouslyupon the hat between them. The two inclined spindles I Il are arrangedto revolve in suitable boxes, and are connected by means of beveledwheels, so that they are compelled to revolve simultaneously in oppositedirections. Moreover, one of the spindles is fitted with a belt-pulley,F', to which the driving-belt is applied. In order that the distancebetween the opposing surfaces of the conical feed-rollers may beadjusted to suit the differences in thickness of different lots of hats,the feed-roller frame K is constructed of sections m n, the upper, m, ofwhich is movable in a vertical direction relatively to the lower, andcan be adjusted relatively to the lower to vary either the distancebetween the adjacent surfaces of the feed-rollers or the inclination ofthose surfaces to each other. To these ends the upper section m of theframe is combined with the lower by means of the yoke L and the pivot S.The sides of Y the yoke L are pivoted to the lower section of the frame,and they embrace the upper section in, so as to prevent its lateralmovement relatively to the lower section n. The adjustment ofthe forwardend of the upper section of the frame to the lower section is effectedby turning the nut j of the screw j', which passes through a hole in thehead of the yoke, and is fastened to the upper section m of the frame,the said nut j being held in contact with the upper surface of the yokeby means of the spring lc, which, in this instance, is made ofindia-rubber. The adjustment of the rear end of the upper section of thesectional feed-roller frame thus described, is effected by the screw 1'.The stem of this screwpasses through ahole in a bracket, s, of the saidupper section, and is held therein by a collar below the bracket and bythe shoulder of the head above the bracket. The body of the screw passesthrough a slot in the hub for the pivot S, and is screwed into the pivotS. The bore of this hub t of the pivot, as seen inFi g. 3, is oblong,and is large enough to permit the rear end end of the upper section m ofthe sectional frame to be screwed up or down the extent required for theadjustment of the feedrollers. The adjacent faces of the upper and lowersections of the sectional feed-roller frame are maintained in contact(so as to prevent lateral movement) by means of a spring, k1, which iscaused to press against the outer side of the hub t of the pivot bymeans of a nut, k2, screwed upon the end of the pivot. The spring kl inthis instance is made of india-rubber, and metallic collars or washersare applied to each of its ends.

The combination of the sections of the feedroller frame by the meansabove described, permits the upper feed-roller to be' moved bodily fromor toward the lower feed-roller, and without changing the inclination orparallelism of their adjacent surfaces, by using both the means ofadjustment-viz., the screwnut' j and the screw a", and the inclinationof the surfaces of the feed-rollers to each other may be changed byusing either of the said two means of adjustment, or by adjusting theforward and rear ends ofthe upper section of the feed-roller frame inopposite directions, as found most expedient for any particular case.

In operating upon hats in a pouncing-machine, it is sometimes expedient(as, for example, during the operation of what is technically termedshaving) to do the feeding by having the feed-rollers operate upon thebrim of the hat alone.

In order that the feed-rollers may be adjusted to this requirement, thefeed-rollers are combined with the pouncing-roller by means of anadjustable transverse connection, which permits the longitudinalmovement of the feedrollers, so that the relative longitudinal positionsof the feed-roller and the pouncing-roller may be changed.

Various adjustable transverse connections, permitting such longitudinalmovement, may be used; but that which I prefer, and have employed in thepresent machine, is a radius frame, N, which is pivoted at its inner endto the main frame D, and has the rear end of the feed-roller frame Kpivoted to it, so that the outer end of the radius frame can move to andfro, and that the feed-roller frame and the feed-rollers connectedtherewith, can be moved longitudinally to vary the longitudinalpositions of the feed-rollers C C relatively to the pouncing-roller Band to the bed A.

In order that the feed-rollers may be secured to in any longitudinalposition to which they it is desirable that the feed-rollers should becapable of adjustment horizontally or laterallyy to the pouncing-rollerto suit such variations. The combination of the feed-rollers andfeedroller frame with the pouncing-roller bed and main frame, throughthe intervention of the pivot P at the rear end of the feed-roller frameK, permits the front end of the feed-roller frame and the feed-rollersto be turned horizontally from or toward the pouncing-roller and bed, soas to adapt the positions of the feed-rollers to variations in thehat-bodies. The holding of the feed-rollers in any horizontal positionto which they may be so turned or adjusted, is eifected by means of theslotted link Q, and the clamp-screw and nut u, the iirst of which isconnected by a pivot with the main frame, so that it may turn to adaptitself to variations in the longitudinal positions of the feed-rollers.

The various combinations and arrangements above described make themachine practicably universal in its application, as they enable itsmembers to be adjusted to suit the variations of the Work to be done byit, which occur in practice. p

When the machine is adjusted, the operation of the bed, pouncing-roller,and feed-rollers upon the hat is substantially the same as that of thecorresponding members of the pouncing-machines in general use.

Having thus described a machine embodying all the parts of my inventionin the best form known to me at present, I claim as my invention- I l.The combination and arrangement, substantially as before set forth, ofthe pouncingroller, the fan-wings arranged upon the shaft of thepouncing-roller, the fan-case, and the jointed suction-pipe extendedfron the fan-case to the pouncing-roller, and having its mouth above thesaid roller.

2. The combination, substantially as before set forth, of thepouncing-roller, the bed, and

the movablepsupport, which permits the relathat one feed-roller may bemoved relatively to the other to suit the peculiarities of the hat uponwhich the pouncing-roller is to operate.

6. The combination, substantially as before set forth, of the twoconical feed-rollers, the inclined feed-roller spindles, the sectionalfeedroller frame, and adjusting-screw at the rear end of the saidsectional frame.

7. The combination, substantially as before set forth, of thepouncing-roller, the conical feed-rollers, the movable feed-rollerframe, and the adjustable transverse connection, which permits of thelongitudinal movement of the feed-rollers relatively to thepouncing-roller.

8. The combination, substantially as before set forth, of thepouncing-roller, the conical feed-rollers, the feed-roller frame, thepivot, which permits the feed-roller frame to be turned horizontally,and the means of securing the feed-roller frame in its horizontalposition.
